Peter Harris Clocks & Militaria has dated this Adams Percussion Revolver 1851 to the 19th Century.

This example is of the scarcer large-bore form, described in period British terminology as .38 bore (approximately .50 calibre by modern measurement). It retains the characteristic robust solid frame, five-shot cylinder with safety pins between the nipples, and a rifled barrel, all engineered to withstand the powerful double-action-only mechanism for which the early Adams revolvers were renowned.

The barrel is crisply engraved:
“DEANE ADAMS & DEANE
30 KING WILLIAM ST
LONDON BRIDGE”
confirming London retail during the early 1850s. The cylinder is clearly stamped “No. 4980” with an accompanying inspection letter, consistent with original workshop numbering.

The revolver retains its original one-piece chequered walnut grip, well-shaped and undamaged, showing only natural handling wear consistent with age. Metal surfaces display an attractive, untouched patina with light commercial scroll engraving to the frame and butt cap. Correct London commercial proof marks are present and appropriate for the period.

Historical Context
The Model 1851 Adams revolver represents Britain’s first truly successful solid-frame service revolver and a decisive departure from earlier Colt-type open-frame designs. During the Crimean War period (1853–1856), Adams revolvers were widely carried by British officers through private purchase, valued for their strength, reliability, and formidable stopping power. Early large-bore examples retailed by Deane, Adams & Deane are notably scarcer than later Beaumont-Adams models and are increasingly sought after by collectors of early British percussion revolvers.

Condition
Good original condition throughout; action operational; cylinder indexes correctly; grip sound; honest age-related wear; no modern restoration or refinishing.
